Brief History

Welcome to the Avionics Division, Hyderabad of Hindustan Aeronautics Limited.

In early sixties, it was strongly felt that our defense services should be more self reliant in defense related equipment, electronics in particular. This resulted in HAL setting up a full - fledged unit to cater to the aviation electronics (Avionics ). Thus Avionics Division, Hyderabad was born in the year 1965.

To begin with, the Division's dedicated design team took up the task of indigenising, the following critical avionics.

  • Identification of Friend or Foe
  • UHF Communication set
  • V/UHF Communication System
  • Automatic Direction Finder (ADF)
  • Radio Alimeter

These systems were developed, qualified, flight tested and inducted into the various MiG aircraft manufactured under licence in India. Later on, the same equipments were fine tuned to meet the requirement of other aircraft like Kiran, Jaguar, Dornier, AN-32 and Helicopters.

Today the Division has spread its wings further to meet the Communication and Navigation requirements of our defense customers and the Division is fully geared to enter the international market too.

Retro - modification
HAL has developed a specialised 'Flight Test Group' with expertise in trial installation of Avionic systems on Fixed and Rotary wings of Combat and Transport Aircraft. This group has achieved success in installing its latest Avionic systems on MiG-21 series, MiG-23, MiG-27M, MiG-29, IL-38, Su-30 MKI, HS 748, and TU-142 series of aircraft and also on helicopters like MI - 8, MI - 25, Seaking, Chetak and Cheetah. It has exhibited complete self-sufficiency for conducting feasibility studies, manufacturing of Mod Kits, Installation and Flight Testing of Avionic systems.
Repair and Overhaul
HAL has excellent facilities and procedures for defect investigation, repair and overhaul of Russian, Western and indigenous air-borne equipment. Our Engineers have vast experience in all these systems and  they also carry out  field repairs. The principle of Inspect and Repair As Necessary (IRAN) is followed, which means that the equipment need not be sent for regular / periodic overhaul. The repair facilities are available from first generation to fourth generation equipment with frequencies from DC to 40 GHz.
